Harmonic analysis, Ergodic theory and Counting for thin groups
Hee Oh
For a geometrically finite group Gamma of G=SO(n,1), we survey recent developments on counting and equidistribution problems for orbits of Gamma in a homogeneous space H\G where H…
Matrix coefficients, Counting and Primes for orbits of geometrically finite groups
Amir Mohammadi, Hee Oh
Let G:=SO(n,1)^\circ and Γbe a geometrically finite Zariski dense subgroup with critical exponent delta bigger than (n-1)/2. Under a spectral gap hypothesis on L^2(Γ\ G), which is…
Effective Equidistribution of Closed horocycles for Geometrically finite surfaces
Min Lee, Hee Oh
For a complete hyperbolic surface whose fundamental group is finitely generated and has critical exponent bigger than 1/2, we obtain an effective equidistribution of closed horocyc…
Effective Circle Count for Apollonian packings and Closed horospheres
Min Lee, Hee Oh
The main result of this paper is an effective count for Apollonian circle packings that are either bounded or contain two parallel lines. We obtain this by proving an effective equ…
